To all whom it may concern:

Be it known that I, BENJAMIN W. TUCKER, a citizen of the United States, and a resident of South Orange. county of Essex, and State of `New Jersey, have invented certain newand useful Improvements in rlype-Nriting Machines, of which the following is a full, clear, and exact description.

IThis invention relates more particularly to the carriages of typewriting machines.

Une of the main features of the invention is to provide a carriage which is extensible to adapt latens either extensible or of relatively di lerent lengths to be supported by said' carriage in order that work sheets of various lengths may be written upon and which carriage is adapted to travel various normal or abnormal distances corresponding to the degree of extension thereof, thereby permitting the writing to take place throughout substantially the length of the platen Without requiring the paper to be shifted from one part of the platen to another part.

Another object of the invention is to provide simple and eiiirient means whereby the platen mav be made in sections and properly held relatively to each other to increase or decrease the length thereof and which platen is supported at its ends by extensible portions of the platen carriage.

Other objects of the invention are to provide simple and efficient means whereby the carriage may be extended and held in .such extended positions; to provide a shiftable paper apron; to provide an extensible scale adapted to travel with the carriage; and to provide simple means for supporting paper fingers to cooperate with the platen and carriage.

A further `object of the invention is to providea simple and efficient escapement mechanism which is so constructed that the carriage may be Vextended or'collapsed and said escapement mechanism operated to, permit letter space movement of the carriage in either its collapsed or extended condition.

A still further object ofthe invention is to provide a' carriage which is particularly adapted for small portable `typewriting machines, wherein certain parts of the carriage are adapted to be moved from a normal op erative position to a. more com-pact one, and

wherein a long carriage would naturally destroy the compact portability of such a machine.

A still further object 0f the invention is to provide a carriage which is simple in construction and which may be readily iliade and assembled.

Fig. 20 is a` fragmentary rear elevation -i the carriage; and

"Fig, 21 is a fragmentary transverse section of Fig. 20 showing the means whereby the paper apron may be adjusted lengthwise of the carriage.

l-'hile the invention is intended more particr larly for a writing machine which is compact and portable in order that the carriage when in a collapsed condition will not be of greater length than the ordinary carriage and thereby interfere with the compact and portable features of such machines, it will be understood that the invention is ada ted for use in connection with writing mac lines ot various kinds and constructions.

The bed 1U may be supported in any desired way to adapt the same for a platen or other case shift, or to be movable from a normal operative position to a more compact one, or otherwise, as preferred. On the bed 10 are two track members 11 and 12, one located at the front part of the bed 10 and the other at the rear thereof. A carriage 13 is adapted to travel along the track members 11 and 12 under the tension ot' a suitable motor, as the usual spring drum, which is not shown, as it forms no part of the present invention. The carriage has two relatively movable base members 14 and 15. These members are substantially U-shaped in cross section, and one member, as the member 15, is adapted to fit within the other member 14. The member 14 is offset for the greater part of its horizontally arranged portion 1U, so that said member 14 bears on the outer surface of the member 15 at the corners of said member 15. The vertical walls 17 of the member 1d are also otset` from the vertical walls 18 of the member 15 for a part of their height and at their lower edge bear against outwardly extending flanges 19 of said member 15. An angular substantially L-shaped plate 2() is secured to each vertical wall 17 and has one portion thereof of each plate fitting under the flange 19, serving to provide a guiding surface for the member 15 when the latter is moved relatively to the member 15 for the purpose of extending or lenfrthening the carriage. Each L-shaped mem )er 2U may have slrbstitntially L-shaped brackets 21 secured thereto, the lower ends of said brackets being adapted to tit under thc horizontally extending portion of the track Ymembers 1,1

and 12, serving to hold the carriage proporly to said track members during the travel thereof. A plurality of shafts 22 are journalcd in the vertical walls 1H of the carriage base member 15, and hold to each ot' said rods are rollsl 23 which are adapted to ridc in (groove/d parts 24 of the track members 11 an Q12, 1n order to assist in permitting the carriage to travel easily and properly along said track. I

0n the carriage base member 14 at one end thereof is secured an upright or end bracket 25, and on the innerA base member 15 at one end thereof is a similar end piece or bracket 26. These brackets are adapted to form the ends for the carriage alidlare movable toward and from each other, according to whether the carriage is extendedor shortened. A platen 27 is adapted to be rotatably supported in the end brackets 25 and 2G. This platen may be made of a plurality of sections arranged end to end so as to be extended the length desired. One or more of the platen sections may be provided of relatively different lengths, adapted to be held in the carriage end brackets ,25 and 26 when the carriage is in its extended or shortened condition as preferred. As shown, the platen 27 comprises a plurality of sections or parts 28, 29 and 30, when in an extended condition, or of only two sections when shortened and of a normal size, but it will be understood that the number of these sections may vary. Each section of the platen may be of the usual construction, having an impact rubber or other member 31, supported by a tubular or other form member 32. A cylindrical hub member or socket piece 33 is secured to one end of the section 28, and said piece 33 is provided with a central ta.- percd opening into which is adapted to it the tapered en'd 34 of an adjustable screw or element 35. On the outer end of the screw 35 is a knnrled head 3G, by which the screw max,r be adjusted for engagement or disengagement with the hub member 33, and said screw 35 may engage a threaded opening 37 in the plate or bracket 25 of the carriage. The opposite end of the Section or platen member 28 is provided with a female socket piece 38. The socket pieces 33 and 38 form supports for theplatcn form 32, which is held thereto, and the socket piece 38 has a central opening of a more or less extended character which is adapted to receive the stem or shank 39 of a male socket piece 40, forming an end .support for the second platen section. This socket piece 40 may have' a pin or dowel 41, which is adapted to enter an aperture in the socket piece 38, so that the two socket pieces 38 and 4() willnot only have a substantial interlocking connection of such a nature as will hold. the two sections in proper alinemen t, but also through one or more of the dowel pins 41, will cause both members to rotate in unison. At the opposite end of the section 2S) is a socket piece 42 similar in construction to the socket piece 38 and adapted to engage said socket `)irre 42 is a socket piece or member 43 similar to the socket piece 4U, said socket piece lll Leeeeer 43 being securely held` so es to forni a part of the pieten section or member BO. If the` plat tfornpriees: more than three seetiooe an adn. lional section may be provided, either of the same or of a different length from the section 29, having similarly arranged end pieeefs` one serving a` mille member sind the other a tenmle member, and which may he connected together or dieoonoeeted as may he required.

In Fig. il the )laten comprises three parte or Sertions, while in Fig.y the middle :eerie tion removed end the two outer sertione, that is eeetione and St), are brought toY gether when it is desired to )nahe the earriage and platen of the usual length. AtV the outer end of the section 3U is a socket pieve or member il corresponding somewhat to the wicket piece 33 of the section ete rep :not inetead of annuler hose heilig arranged on the. outer surface of the flan e. en elongated portion or hoes 45. n'mided., Figs. i3 and le. which is adapted to enter a `elot or groove il in the hof-e ET of a yeleeve tti. The purpose of the elongated portion or hone 45 in to adapt the platen as n whole to he readily inserted in the Sleeve or renioved therefrom, and by reason of .eaid hose being elongated the Sleeve and pieten may be mede to rotate together.

The sleeve 48 ie held in :in opening in the carriage end :'I and said sleeve is threaded at 4t? at one end thereof, and seid threaded opening in engaged by the threai'led portion 5U of a eerew fil. The sere-i: 5l has a tapered portion at one end adapted to engage a` tapered opening in the boeket` piece 4+.. and at the oppoeite end ofseid screw is a knnrlerl head 53. A knol) 54 is held by a` srrew 5.3 or otherwise to the sleeve 4S and srrew .l to adapt the lmoh and sleeve. ae Well as the Soren' 51 and the plnten aS a whole to he rotated mantntlljtr h 'v hund and to move the nio-l; sheet about the platen in the nena] way. ly releasing the screws 35 and 51 from engagement with the end socket pieren` the platen may he removed by sliding?` the ho; 'l5 to one side ont` oi theV groove 4G, whieh will permit the section 2S) to be removed or inserted in place, and if removed Will permit the eee tion 30 of the platen to be connected with the sertion :28 to shorten the platen, as Shown in Fig. 5. ln this ligure the carriage members 'il and l5 have heen moved relatively to earl] other to collapse the rarriage. and hv tight:n ening the Screw 5l the platen as (hns shortened may he properly supported in the earringe between the serewe 5l and lh.

The rarriage may he held in its,` lengthened on' shortened position in nny desired way. :Le one 1nean. ,a rod 5V is rotatably held in a 'ng Sti eit'teinling` downwardliv from the horizontal plaie portion ol the carriage Ineniher 15 ind the mirri-aire end hrzacliet 2li. (ln the rod it? a dog Il?, Figs. ti and f), which in adapted to he moved into engagement, with one or more openinge, as 5Fl` in the member lh arrording lo the ditl'erent extensions ott the earriage to adapt the ezi1iage for the dill'erent lengths ot' platens, Whether the platen is made up ot' a plurality of sections, or a serie;1 of platens are employed of rela` tively dtt'erent lengrtlw4 to adapt one platen to he enlintitllted i'or another. At the other end ot the rod 5t? ie a lever fill, the upper end of whirl] is proiided with a linger portion ott to .adapt the dog to he released from engah'einont with the openingle` there living; a pl-infr it lle-aired. tendinrY normally to keep tlnA log in engagement to loelY the two rar riale nnndnrn` 1l' and l5 against` relative lnoionnnt.

line ot Ille importent` faitnrw` ol' the present, invention is the provision of means wlnn'ehi' the marriage may have relativrl \r ditlirenl lrngtlwV ot' feed, according to the length ot the rarriagre :mit platen. That is, the letter feeding` merhaniem is so ronfatrnrfed that the carriage muy travel nor` nml :ind ahnornnil distances rorrenpomling exart lj; lo its length. lf the carriage is short, or ot' normal length-` as shown in Fig. .'3, the leiter leed movement is eo uonstrnrtm'l that the rol-ringe inni' he t'rd with a letter Spore movement along the rarriage hed to the usual extent l'or ordina ry writing; lnlt il' the rm'- riagio if: extended as shown in Fig. (l. the name letter t'eed nieehaniem without special :nlinetnnfnt ie adapted to ranse the earriage to feed i ,greater extent. arrording' to the. ex tent to whirh the carriage and platen have heen lengjtlirned.

The sets olE dogs l2 and l'tl and the Carriers (it and (i5 for nmid dotre nro Similarly ronstrln'ted. liar-l1 rarrirr is in the forni ot' an arm, which is pivoted at titi at one end, and ia guided in a hrarltrt lli' at, the other end and hoth are monnted on the inner carriage hase member l5 to partake` of ite collapsed or extended movement'. A fixed dog 1S is held to eaeh oarrirr and a loose or linda-r dog (i9 is pivotalljr held to earl] carrier, the lilnher do;r lie-ingY l'orred in one dirertion hy means of a Spring TIL while the rarrier itself is foreed in one direc-tion by :i Spring Tl. The fixed and lilnher doge and the rarrier (il operate in the nnnal way, and taken as a single element the dogs and either ot' the carriere- (il :unl tfi are substantially the saine as ein bodied in the Corona typmvriter, dill'ering. however. from the aid Voi-una. typewriter in that there are two dog carriers instead of one which permit of an abnormal travel of the Carriage. and the present` Construction differs further in that the raek is mounted upon the carriage hed` and the dogs; and earrier mounted upon the carriage hed to travel therewith. though the reverse of this eonstruetiou may he employed it desired. The dog rarriers are eat-h provided with a lug or arm TL. and these arms are eonneeled hy a rod T3 whereliy the two dog earriers move in unison. andthe dogs ot' said Carriers are so positioned that` the)r may lloth engage, the` teeth ot' the rat-lt at the same time. or one only` aeeordiug to the position of the earriage relatively to the rarlt. ln this 'ay the farriage mai he made lo travel along the hed through the action ol' one set oi de fs and the usual tension merhanism. and for a part ot' its travel both sets ot dogs may engage the teeth ot the raelt and the carriage may still travel until the first set ot' dogs has lett'y the rarlt. while the letter sparin; lr movement may he rontrolled hy the seeond set ol' dogs. Thus the two sets ot' dogs may operate in unison and at the same time on the rael( or either set ol' dogs operate to rontrol the letter spare movement ot therarriage. l this ane-ans long sheets ot' papel' or large emi-hips may he written upon sull slantially throughout their entire width or length without inrreasing the length of the raek. and said means adapts the rarriage to he lengthem-d or shortened without intertering;A in an) way with the letter feed movement thereof.

The eseapement dogs may he operated in any desired way. 'llhe earriage lard. lll may lie provided with a slot 7l. in whieh is adapted to retiprorate an element T. 'lllis element T5 is operatively eonnerled io the, universal har. not shown. and is adapted to lle moved at eaeh depression ol the hey- `operated levers or the spare liar. in the usual way. 'l'he element To is adapted to engage a transversely extendiner llar Tt. This liar TIS is made in two parts so as to he extensilile. as liest shown in l'itf. I. and ltigs. il to ll. The har Tl has` two nu-mliers TT and T8. The nlemher TH is provided with an en larged end T) haringr heut lips or portions to lit over the hotly ol' the memher T7. and the lnelnher TT has an enlarged end Htl provided with overlappiiugl engaging portiona adapted to span and slide upon the llody of the liar inemller TS. n arm extendsK upwardly from the memla-r 7T and is pirotally held :it Si to the rarriagfe end or ln'aeket 25, and the memller TH hasl its; outer end extending' upward and is pivotall \y held at; H2 to the rarriage end lualltet tft". A lever H25 is pivolally held on the srrew or pin Si and has a sullstantially U-shaped portion Hl. whieh is adapted to engage one edge oldhe upwardlyr extending' portion ol' the eat-ringe release har Tt and in sueh a way that' said bar may he znovediinwardly independent of the movement of said lever 83. The transversely extending har TG is normally forced in one direction hy a` spring 85, While the lever S3 is normally t'oreed in one direction hy an independent spring SG, there being a stop 87 adapted to limit the movement of the lever 83 and the carriage release lmr in one direction. AS the element 75 is operated by the univerbal bar. it will rock the extensible har 7f3 on its pivot screws, independent ot' any movement of the lever S3, and Sneh movement ot' said liar will engage the fixed dingr (SH ot' either one or both sets, so`af1 to permit the carriage to he. letter spaced in the usual way. The release ofl the eseapement independent of letter Space movement may he readily aeeon'iplished by means ot' the lever S3, which will move the release and operatilw har Tl' in a manner similar to its; movement hy theelement 75.

The carriage. may lie provided with the paris" usually eoperating therewith to adapt the work Sheet to he properly held about` the platen. lVhere the platen is extensilrle. as in the present eonstruetion, it is desirable that the paper apron he also either eXtensLihle or that it la;y adjustable to permit it to he substantially centrally loeated with respect to the position of the carriage ends. AS shown, the paper apron H!) is adjustable lengthwise of the platen. The paper apron is in the torni of the usual plate. adapted to direet the paper properly about the platen. and aty the Vtoriw'ard eind thereolE may have detarhahle or otherwise mounted thereon a feed or preasure roll U0, adapted mn'lually to hold the work sheet so as to more with the platen lor line Spacing orotherwise. The paper apron leurres u \\ardll' and waren-willy in Hustantially t e t'orm of au o e'ee eurre. and is held to ln'aelcets ill. rl`he lu'aehets ill extend upwardly trom a slide U2. This. de D2 hasends turned inwardly and adapted to en age a substantially Twshaped guide tti, mounted upon the niemher 14 of the carriage. A. dog SM is held to a rnd U5. and said dog' has its lower end adapted to engage an aperture or openinl.;Ir in the guide J3 \\'l|ere| \V the paper apron HU and the slide 9'! may lle adjusted relatively to the platen and by means of the doo- !,li positively held in sueh adjusted position. The dof; is adapted to lio released for adjustment hy means ot a linger lever 9F, and said dog is normally forced to an eingaging position hy means ot' a spring 97 arranged around the rod 95 or in any other desired way.

'lhe pape apron Si) may he moved on its pivot rod J5 hy means of a eanl device 98. said din ire heine held to the upper end of a guide braeket JU or otherwise supported. and said deviee 9S may lle normally forced in one direetion lay means of a spring 100,

miger there being a spring or other oleane pro vided whereby the. pressure roll may be normally forced against the platen.

n extenijihlo seule may be mounted upon the forward end ol' thei rari-lage tirar-li t and t. This ,scale ma); eoafririt ol tn members lOl and lll-.2. Thea@ lnemliere Slide, one npon the other, and one ot' said ineinlwrr-a as member 102, may have it@K upper and lower edges at @noeud bent over to Vforni overlapping lipsl 103. and the ineinher llli' may have overlapping' lips 1G53 l whit-.h the two membersl are alidingly held together. One member ot' the scale may he held to one of the ond pieee, as the ineinlier V10:.

to the, end pieve of the Carriage 261 and the, other member Uli o? the scale nia.;Y he held to the carriage end pieee or bracket E35. Thus, as the carriage is extended, the ntl pieces will Carry the respective inemliers of tho Seale tlierewith` The earriage may he alo provided wit paper lingers lll-l. These paper lingers at their upper ends may have rollers 105 to engage the paper or work about the platen. The body ot tbe paper lingeri-A [nair he in the torni ot' narrow metal strips. and at their lower ends m: j," each have a Substantially C- ehaped part 10G, whieh is adapted to sliding-li hold eaeh paper linger upon a ruido lair. Une of the paper fingers is held to a har IUT and the other linger it; held to a har ltlh. The bar 10T is held to the carriage end piece 2li, and the har i053 to the Carriage end plee;- 23, no that said bari-` tnt15F be externled. or moved relativelyT and with the end pioeeel during the. eXtenSion of the carriage, and hwel: extension will also cause tho'tingers to nioie therewith. and h v reason of the eonneeiion helweein the paper fingers and the hara Said tingersmay be adjunted to the desired dint-aine for properlyF holdingr the, worh about the platen.

lt will he understood `that any desired toi en olb line spacing: mechanism may he einploved to rotate the platen. Ab one means. a ratehet `wheel 10J is held to one end ol' the platen and adapted to engage the teeth ot the ratchet wheel ia a pawl llt) mounted upon t lever 111. The movement ot the, pawl and the nnmher of teeth engaged there.- hy ie controlled hy a stop. as 112, Fig. 3, to adapt the. platen to he rotated a single. donhle, or more spaces. This nieclmnialn,y however, in substantially the same as that employed in the Corona typewriter, and is not claimed speeitically herein, it being eliown for the purposey of illustrating how vueh nnwhanism may be mounted in a earriaie ifonetrueted and operating' in the inanner dihelosed herein.

lt will be evident that h v the construction uahown Simple, means is provided wherehv the: platen mayr be lengthened or hhortened or tho carriage lengthened or shortened;

that. elli-e ive mean` provided whereby the earriage may travel various normal and abnornnil distances aerfording to whether the earriage and the platen are lenglhenetl 0r ehortem-d. and without the necessity of interfering in an; wav with the feeding meehanianx; that hsimple and el'lieient means is prm'ided whereby the earriage may travel properlyY along its bed: that simple and etliuieut mseapement meebaniani is provided to adapt the rarriage to have normal and ahnornial travel; that the Carriage is so eonatrnetefl that it may be readilyv made and assembled and the parts thereol' positively held against relative niovennnt hoth in its lengthenerl and shortened eondition; that simple and ellieient means ia provided where,- b v a paper apron may be adjusted lengthwise of the marriage; and that lsimple means ia provided whereby the cooperatingr parts nauallxY employed in eonnection with the platen and as a part of the carriage are so f-onstrueted that they ma)Y perform the usual l'unetion and properlyY r'ooperate with the platen lo hold the work while being written upon.
